Patent number: 7257336Abstract: In case of a developing density correction based on a test image (patch image) density, normally, the developing density is carried out in a short period of time by correction (? correction) of a developing bias and a grid voltage (S11). When a correction amount of the ? correction exceeds an ordinary range, the ? correction (S11) and adjustment of toner concentration (magnetic permeability reference value) (S5) are carried out in combination. Furthermore, when the toner concentration is changed, the setting of a correction reference of the ? correction (? correction TBL) and correction timing of the ? correction are accordingly changed (S6, S7). Therefore, in the developing density correction based on the test image density in the developing device using binary developer, it is possible to carry out the developing density correction, which is carried out in a short time, and whose correction width is wide, while maintaining the accuracy of a developing density adjustment.Type: GrantFiled: January 13, 2005Date of Patent: August 14, 2007Assignee: Sharp Kabushiki KaishaInventors: Masayasu Narimatsu, Masakatsu Hayashi, Hiroshi Kawamoto, Makoto Uehara, Jitsuo Masuda

Patent number: 6215968Abstract: A high density detecting toner pattern is formed on a photosensitive body and a high density correction is effected by comparing a value detected by a reflection sensor with a high density reference value so as to maintain an image density at a specific level. An image density correcting section adopts a result of the preceding high density correction as the high density reference value, and compares the same with a result of a current high density correction. The image density correcting section effects the half-tone density correction only when a difference reaches or exceeds a preset difference reference value by forming a half-tone density detecting toner pattern on the photosensitive body and comparing a value detected by the reflection sensor with a half-tone reference value. Consequently, it has become possible to provide an image forming apparatus which can maintain a density output of an entire image at a specific level for any kind of images including solid, line, and half-tone, etc.Type: GrantFiled: April 7, 2000Date of Patent: April 10, 2001Assignee: Sharp Kabushiki KaishaInventors: Makoto Uehara, Toshihiro Ohta, Yasutaka Maeda, Takashi Kitagawa, Katsuhiro Nagayama, Shouji Tomita, Kaori Dakeshita, Daisaku Imaizumi
